Abstract
This invention is related to a transparent glass tube evacuated from air and other gases. To prevent the transferring of heat. This glass tube contains reflective mirrors that focus on the sun rays, the shape of these mirrors are (parabola). The evacuated glass tube also contains liquid carrier made of metal or glass that goes through this parabola so that the sun rays focus on it. This liquid carrier tube is coated with absorbent coatings of sun rays. Any liquid substance transferring heat, such as oil goes through this liquid carrier tube. These evacuated glass tubes can be used individually or placed in rows on a metal holder and moved according to the movement of the sun. So that the parabola mirrors are directed towards the sun then the solar rays focus on all sides of the liquid carrier tube. Then the oil will become hot and goes wherever place which it can be useful in heating the steam turbine boilers and heating swimming pools and in factories. These tubes are made in different sizes, diameters and lengths as needed, and their size is proportional to the size of the reflective mirrors and the liquid carrier tube, FIG. 1.
Description
- This invention relates to solar thermal collectors that collect sunlight to benefit from the heating of liquids. Those solar thermal collectors are three types as follow:
- First: is a vacuum glass tube containing a metal plate that extends along the tube diameter and in the metal plate mediate there is a conveyor tube for liquids. It must be moved according to the sun and the liquid is not heated until the metal plate is heated, so the metal plate keeps a certain amount of heat due to the amount of the large metal. It begins to transfer the heat out by the radiation that the vacuum cannot block.
- Second: A vacuum tube with inside conveyor tube for liquid, in which part of tube surface is exposed to the sun and no concentration of sunlight occurs. The diameter of the conveyor tube for fluid should be close to the diameter of the outer tube so that it has the largest area exposed to sunlight. We have a large amount of fluid that is difficult to raise to the required temperature, although this liquid is very expensive oil.
- Third: Third: identical to the second type, but behind it there is a reflective mirrors focus the rays towards the vacuum tube. Its disadvantages are vulnerable to various weather conditions such as shelling small sand grains that scratch and reduce its efficiency. The dust particles, which attach to the mirrors, block the light and disperse the sun from the absorption tube. The airborne dust particles in the area between the mirrors and the absorption tube affect the solar radiation, absorb part and disperse part. The absorption tube itself is exposed to collecting dust on its surface.
- Therefore, there are three stations of dust, on the mirrors, on the empty tube and in the zone of separation between them. The disadvantages of this type is the need to a large quantity of metal pieces to install the mirrors with the glass tube, so as not to be driven by the air. Any movement moves the focus rays away from the target. In addition to the cleaning difficulty because of mirrors curved shape, the slave thickness, and the cleaning difficulty of the tube because all aspects needs to be cleaned and it is difficult to clean the tubes vertical shape on the mirrors.
- This invention relates to the transparent vacuum tube. This transparent glass tube consists of reflective mirrors (parabola). There is a fluid conveyor tube coated with coatings that absorb solar radiation very much in front of these reflective mirrors and focus of collecting solar radiation. The function of the fluid conveyor tube is to transfer any liquid material, such as mineral oil that absorbs heat and transfers it to where it is needed. The fluid conveyor tube is located inside the vacuum tube. The purpose of the presence of the mirrors and fluid conveyor inside the transparent vacuum tube is to protect it from dust and its effects in blocking solar radiation and damaging mirrors and fluid conveyor tube. So, by this invention, we overcome the devastating effects of dust and grains of volatile sand that scratch the mirrors. In this invention, cleaning is easy, because the need for cleaning is limited to the upper part of the tube opposite to the sun. It is easy to clean because there are no racks and vertical barriers above the tube that impede the cleaning movement as mentioned above. It also has a life span longer than the others because of there are sensitive components inside and low cost when putted on racks, so it need not many links of metal pillars in
